Abstract
In an integrated circuit, a data link relies on low swing differential signals. A push-pull driver circuit and a receiver circuit are both clocked from a common on-chip clock. A driver circuit includes an H-bridge of NMOS transistors and a line-to-line precharge circuit which reduces the power requirements of the circuit. A clocked repeater within the link may itself comprise a clocked receiver and an H-bridge driver with line-to-line precharge.
